selectors received in Split-Include attributes (might have been different

client releases an error notify (ATTRIBUTES_NOT_SUPPORTED).
We also can't install the IPsec SA with all configured subnets as that
would cause conflicts if the client later negotiates SAs for other subnets,
which iOS 8 does based on traffic to such subnets.

For Shrew and the Cisco client, which propose 0.0.0.0/0, we still need to
override the narrowed TS with 0.0.0.0/0, as they otherwise won't accept
the Quick Mode response.  Likewise, we also have to narrow the TS before
installing the IPsec SAs and policies.

if we received 0.0.0.0/0.  Since we don't get the original TS in the

kernel-wfp: Install outbound ALE connect rules for IPsec

Similar to the inbound rules, the ALE filter processes IP-in-IP packets for
outbound tunnel mode traffic. When using an outbound default-drop policy,
Windows does not allow connection initiation without these explicit rules.

kernel-wfp: Install inbound ALE IP-in-IP filters

When processing inbound tunnel mode packets, Windows decrypts packets and
filters them as IP-in-IP packets. We therefore require an ALE filter that
calls the FWPM_CALLOUT_IPSEC_INBOUND_TUNNEL_ALE_ACCEPT callout to allow them
when using a default-drop policy.

Without these rules, any outbound packet created an ALE state that allows
inbound packets as well. Processing inbound packets without any outbound
traffic fails without these rules.
